Moreover, with the assistance of grey series forecasting model and the rule of the annual precipitation, the annual average precipitation, groundwater flow field, groundwater level and spring flow in the future under current exploitation circumstances were forecasted. If 2010 is a high flow year (guarantee ratio 20%), or median flow year (guarantee ratio 50%), or even low flow year (guarantee ratio 75%), the underground water level of Heilongdong spring in flood season will exceed 130 m, or reach 130 m, or even below 130 m, and the spring flow in flood season will exceed 10 m^3/s, 7 m^3/s, 5 m^3/s respectively.

以灰色序列预测模型为辅助手段，结合历年的降水规律，对未来现状开采条件下的年均降水量、地下水流场、水位及泉流量进行了不同保证率条件下的预测，若2010年为丰水年（保证率20%）、平水年（保证率50%）、枯水年（保证率75%，黑龙洞泉汛期地下水位标高分别为超过130m、达到130m、低于130m，汛期泉流量分别为超过10立方公尺/s、7立方公尺/s、5立方公尺/s。

Average annual precipitation data of the last 30 years from 1961 to 1990 at 186 meteorological stations in Gansu and its nearby regions was compared and analyzed by Inverse distance weight tension, Spline, Ordinary Kiging methods. The result showed that the three interpolators could reflect the spatial distribution of precipitation of Gansu province. Ordinary Kriging method was the most effective, followed by Spline methods and Inverse distance weight tension method.

利用甘肃及其周边186个气象台站30年平均降水资料，分别采用了反距离加权法(In-verse distance weight tension)、样条函数法和普通克里格法等3种常见的空间内插方法较为系统的分析比较了这3种内插方法插值结果，结果表明：3种方法的结果都基本上反映了甘肃降水大体空间分布规律，而普通克里格法的插值效果最好，样条函数法次之，反距离加权法较差。

By analyzing the changes of precipitation ratio, particle size and morphology, the effect of the impurity ingredient contained silicon on the process of precipitation of sodium aluminate was studied.

Using the relative reflection as weighting factor, the weighted mean of the surface albedo over Dunhuang Gobi in typical arid region is calculated and its values are 0.255 ± 0.021. After canceling the interference of the buildings, the mean values of the roughness length averaged with logarithm is 0.0019 ± 0.00071 m. After removing the influence of the oasis, the soil wetness factor computed with data under condition of no precipitation is 0.0045. After removing the influence of the precipitation .the mean values of the soil heat capacity over Dunhuang Gobi in typical ac-id region is 112 × 10 ~6 m~(-3)K~(-1), a bit smaller than the values observed i n HEIFE. But the soil heat diffusivity and conductivity are about one of those observed in HEIFE. The soil water content over Dunhuang Gobi in typical synoptic condition is very little and does not exceed 1% basically.

并且利用相对反射为权重加权平均，计算得到典型干旱区敦煌荒漠戈壁的平均反射率为0.255±0.021；剔除建筑物干扰后，利用对数平均法计算的粗糙度长度平均值为0，0019±0.00071 m；剔除绿洲影响后，用无降水影响的资料确定出土壤湿度影响因子为0.0045；剔除降水影响后，用观测资料计算的敦煌典型干旱区荒漠戈壁的热容量平均值为1.12×10~6m~（－3）K~（－1），比&黑河试验&在戈壁和在其它沙漠观测的有关值略小一些，但热扩散率和热传导率都比&黑河试验&在戈壁观测的值小一倍左右；观测的敦煌戈壁典型天气条件下的土壤含水量非常小，基本上不超过1％。

Of the three tropical precipitation clouds in winter in Hainan the water vapor content is the highest in cumulonimbus and varies most greatly during precipitation, the second highest in cumulus congestus and the lowest in stratocumulus opacus.
